靺師迦花（舊云婆師迦花梵語訛也正云靺㗚沙迦此云雨時花也或云夏生花其花白色甚香半夏時生因名云）。

Vārṣika flower [靺師迦花] (Formerly called poshijia flower, which was a corrupted Sanskrit term; properly it is vārṣika, which here means "rainy-season flower"; it is also called "summer-blooming flower"; its blossoms are white and very fragrant; because they bloom during the summer retreat, it is named accordingly).
